Hyundai Repair: Signals, body control module bcm, turn signals

Question
My right signal does not shut off even when the car is off.  I was told that the wiring needs to be replaced by a new box??  $920 to do.  Then someone told me that this happens to 03 Tiburon's a lot.  They said there is away to soder the wires back together and it will work once again.  Do you know about this?

Answer
Hi, Craig.  I'm sorry it's been so long for you to receive an answer.  It appears that a previous expert left and the questions he didn't answer were simply dumped into the system.  I didn't check here very frequently because the questions all appeared to be at least six months old.  If you are still having the issue and need more information than I've provided, please follow-up with me.

I also think I may have addressed this with you already, but in case I haven't here's some info.  The turn signals in your car are controlled by the body control module (BCM).  In fact, there are relays inside the module.  If you're able to disassemble the module and replace the relays (which will require unsoldering and soldering), you may be able to repair the BCM.  Most likely, however, you'll be stuck with purchasing a new BCM.
